WA ER-Moron.

To all whom it may concern:

Be it known that I, EDWARD D. WARNER, citizen of the United States, andresident of Pelham Manor, in the county of Westchester and State of NewYork, have invented certain new and useful Improvements in W Vater-Motors, of which the following is a spec1fication.

The invention relates to water drlven motors in which a rotor is rotatedby the action of a jet of water on the buckets thereof, and more ablemotors adapted to be operated by the flow and'pressure found in thewater sup ply usually furnished for household and V analogous purposes,and designed for de veloping the power required for driving massagevibrators, polishing'wheels and the like, and the object of theinvention is to provide an efficientmotor of this character, which shallbe simple in constructlon, economical in operation'and particularly welladapted to serve efficiently with water-sup ply systems of widelydifferent pressures.

Another important object is to provlde a rotor having its buckets soshaped and disposed as to utilize the force of'the wateradvantageously,'and a further object is to provide stationary vanesadapted 'toserve with such buckets and upon which the cur-' rentmay'react to increase the power developed. V .7

A further object is to provide a coupling especially adapted for servicewith such motor for holding the tools or implements driven thereby andpermit them to be readily attached or detached in substituting one foranother.

The invention consists in certain novel features of construction andarrangement of parts, by which the above objects are attained, to behereinafter described and claimed: 7 The accompanying drawings form apart of this specification and show an approved form of the inventionFigure 1 is a vertical diametrical section, partly in elevation.

Fig. 2 is avertical transverse section through the casing and itsattaching means, with the rotor shown in side elevation.

Fig. 3 is a perspective view of a socket adapted to receive a tool orits holder.

or tool holder adapted to be received held in the socket shown in theprecedlng figure.

Similar numerals refer to the same parts in all the figures. v

1 is the shell or casing of the motor which may be understood to be intwo'or more parts suitably joined as m venient and economical inmanufacture, .to provide an internal recess of approximately circularform adapted, to inclose a rotor fixed on ashaft' 4 'extending axiallythrough the casing and'recess and adapted to rotate in bearings therein.f At the top of the casing is a hollow neck 3. having means forattaching the casing to a faucet or'other device for .the discharge ofwater, and having an internal cavity; From the interior of the neckbelow the nlpple, extends an angularly arranged passage '10 adapted todeliver water in a jet to the, rotor. The latter comprises a circular aybe found condisk 5 having acentral conlcal boss 7 on its inner face,extending the full width of the recess from such face totheopposite wallof the casing. On the plane circular margin of the disk is a seriesiofwings or buckets 6 extending part way to such opposite wall,

preferably cast integrally with the casing,

line approxi-I fixed vanes 8,

extending inwardly within the line of the V buckets 6 and between theirstraight inner ends and the boss .7. The edges of the vanes 8adjacentthe boss are curved to conform to the curve of the latter, andthe vanes extend across the space between the buckets 6 and the wall ofthe casing carryingthe vanes.

The lower end of the casing is open, as at g), to provide a dischargeorifice through which the water may escape unobstructedly afterperforming its work inthe casing, and the orifice may be of such sizeand form as may be best adapted for general service.

The overhung end .of the shaft 4 may be shaped as desired to receive anysuitable extension thereof;

as shown n Fig. 1, it-is hole adapted to receive a pin by which aflexible shaft, as 12, see Fig. 3, may bejoined thereto. 7

At its free end the flexible shaft is joined at 11 to a cylindricalshell or socket 16 having a longitudinal slit or deep notch 13terminating at 14 in a short laterally or circumferentially extendingnotch 15, forming a bayonet lock with a pin or lug 21 on a cylindricaltool-holder 22, adapted to be inserted in the socket 16 and held by'theengagement of its pin in the notch 15, and having a collar 20 serving asa stop to limit its insertion within the socket, and a spindle 19adapted to receive a polishing wheel or other rotatable implement.

In the event of a T shaped slot being cut in the cylindrical shell orsocket 16, it will be possible to rotate the combination in eitherdirection 17 or 1 8. t The operation of the motor is as follows: Waterentering the casing as a jet from the passage 10 strike the curved ends,of

the buckets hand by its impact forces the rotor and its shaft to rotate,as the bucket advances under such impact the velocity of the waterlessens and it follows the straight portion of the bucket and isdeflected thereby inwardly toward the center along the plane face of thedisk and along the surface of the boss or cone 7 guided by the latter tothe apex and into the space beyond the buckets where it arrives in aspent condition, out of the path of the buckets and is free to escapethrough such space to the discharge iopening 9. Thus constructed themotorwill perform at a high rate of chiciency but experiments indicatethat the efiiciency may be increased by the introduction of the fixedvanes 8 upon which the water reacts as it is delivered inwardly andspirally upon the done from the buckets, and

escapes fully spent with all its energy imparted to the rotor.

Importance is attached to the space between the rotor buckets andopposite wall for permitting the spent water to escape freely andimmediately after it has performed its work, and to the conical boss bywhich the water is led to such space at the center of the rotor wherethe rate of velocity is less and entirely out of the path of the rapidlymoving buckets.

The fixed vanes may be omitted and other modifications may be made inthe forms and proportions of the parts as found necessary or desirablein adapting the invention to various conditions of service.

I claim I 1 In a device of the character set forth, a casing having aninterior recess, a passage leading thereto from a supply of water underpressure, and a discharge opening, a disk mounted to rotatein saidrecess, having aseries of buckets on its margin ar-c ranged to receivewater from said passage, said buckets" having a width less than saidrecess to afford free escape of spent water to said opening, through thespace thus provided, a conical boss on said disk within said series ofbuckets, and extending into such space, and a series of vanes on the interior of said casing within said series of buckets and extending acrosssuch space, said vanes having their edges adjacent said boss shaped tocorrespond to the shape of the latter. 7
